This paper proposes a new method for 3D delineation of single tree-crowns in LiDAR data
by exploiting the complementaries of treetop and tree trunk detections. A unified …

In this paper four different delineation methods based on airborne laser scanning (ALS) and
hyperspectral data are compared over a forest area in the Italian Alps. The comparison was …

Forest canopy structure influences and partitions the energy fluxes between the atmosphere
and vegetation. It serves as an indicator of a variety of biophysical variables and ecosystem …

Accurately simulating the area ratios of the sunlit and shaded foliage in multiple-view angles
presents a challenge in developing a geometric-optical (GO) model. GOST model by Fan et …

Canopy layers form essential structural components, affecting stand productivity and wildlife
habitats. Airborne laser scanning (ALS) provides horizontal and vertical information on …

LiDAR-based techniques to estimate forest variables at the stand level require accurate
calibration through ground truth data. One purpose of this study was to verify whether angle …

The canopy density model (CDM), a new product interpolated from airborne laser scanner
(ALS) data and dedicated to forest structure characterization is presented. It exploits both the …

This study applies an approach based on stochastic geometry for retrieval of forest
characteristics from airborne laser scanning (ALS) in two situations: 1) without ground …

In order to retrieve gap fraction, leaf inclination angle, and leaf area index (LAI) of
subtropical forestry canopy, here we acquired forestry detailed information by means of …

In this paper we present a hierarchical approach to the segmentation of high-density LiDAR
data which aims to automatically detect and delineate the single tree crowns of both the …
